Compared to the 2022 rankings, the Japanese brand Lexus has regained the top position from Kia in the overall list, as well as surpassing Genesis in luxury segment. Last year, Lexus was modestly in 5th place, behind both Toyota, Hyundai, and Buick.

The ranking is the result of J.D. Power’s research after 3 years of car ownership, which means the main audience is 2020 models. The study is conducted annually, usually published in the second week of February 2. J.D. Power is a global marketing information services company, headquartered in Troy, Michigan, USA.

The study surveyed hundreds of problems arising in 9 main categories: air conditioning, driver assistance, driving experience, exterior, characteristics/control system/display, infotainment, interior, powertrain, and car seats.

Research has been carried out regularly for more than 3 decades, but some changes over time as cars are also upgraded following model or generation, and now the study assesses owner satisfaction with the operating condition of the car after three years of use.

The reliability score is ranked on a 100-point scale when the study will tally troubles and damages per 100 vehicles (PP100). This means that the fewer points the brand has, the less trouble it will have.

Accordingly, Lexus has the best score out of 33 car brands, with 133 points.

The 2022’s No 1, Kia, dropped to 3rd place while another Hyundai sub-brand, Genesis, moved up two places compared to 2022. Parent company Hyundai is in 8th place, right behind Toyota.

Interestingly, the budget car has an average PP100 score of 182, 23 points lower than the average of luxury cars (205). Luxury brands such as Jaguar or Mercedes are in very low, while still at the bottom of the table is the familiar brand Land Rover. According to J.D. Power, the reason for the difference comes from the fact that high-end models often have newer features.

“The gap between the two segments has been quite large since the study was conducted 34 years ago and reflects a trend that began in 2016. The disparity is the new technology in the car, as luxury cars often have more technology – which increases complexity and creates additional troubles,” J.D. Power said.

According to the study, the most common problems were related to the infotainment system, with an average of 49.9 points, and 6 of the 10 most troubled areas were related to the system. Features listed include Android and Apple connectivity, voice recognition, and touchscreen sensitivity.
